Adamek, a former cruiserweight and light heavyweight titleholder, will face Grano in a scheduled 10-round bout on a "Fight Night" card (NBC Sports Network) at the Mohegan Sun resort in Uncasville, Conn. The card was announced last week, but Adamek did not have an opponent.

"This matchup is [between] two guys that are right in front of each other and can punch," Main Events promoter Kathy Duva said. "Either can go at any time. This promises to be an exciting brawl."

Poland's Adamek (48-2, 29 KOs), who lives in Jersey City, N.J., and has become a major draw in New Jersey, will be in his first fight since signing a new promotional deal with Main Events.

Since being overwhelmed in a one-sided, 10th-round knockout loss in Poland against heavyweight titleholder Vitali Klitschko in a September 2011 championship fight, Adamek has won four consecutive fights. However, he is coming off a highly controversial split-decision victory against former cruiserweight titlist Steve Cunningham in December in their rematch.

After that fight, Adamek, 36, sought out offers from promoters when his contract with Main Events expired but ultimately returned to the company that has promoted him since 2008.

The contract situation led to a longer layoff than Adamek is used to, but one he thinks will do him some good.

"After fighting four fights in 2012, I was able to take a rest," Adamek said. "Now I feel I will be able to get back in the ring refreshed and remind all my longtime fans what the 'Mountain Boy' is really about."

In 2012, Grano (20-3-1, 16 KOs), 32, of Hartford, Conn., won both of his fights by knockout, a third-round stoppage of fringe contender Brian Minto and a fourth-round knockout of former title challenger DaVarryl Williamson. However, Grano is coming off a 12-round decision loss to Eric Molina on April 27.

Still, Grano is a brawler with good power who figures to match up well with Adamek.

"I understand Grano is a fighter who really comes to fight," Adamek said. "I intend to do the same. I think all of our fans will be pleased on Aug. 3rd."

Said Grano: "I am very grateful for this opportunity. I'm excited to fight Adamek. Adamek comes to fight, as do I. This is going to be a great show for all of our fans."

Brooklyn, N.Y., middleweight Curtis Stevens (24-3, 17 KOs), who recently dropped down in weight from super middleweight, will face Saul Roman (37-9, 31 KOs) of Mexico in a scheduled 10-rounder in the main event.

Longtime Philadelphia heavyweight contender Eddie Chambers (36-3, 18 KOs), who suffered a decision loss to Adamek last June, is also on the card. He is moving down in weight to cruiserweight and will face southpaw Thabiso Mchunu (13-1, 10 KOs), who will be fighting outside of his native South Africa for the first time.
